"The overall image quality was one area where I was very impressed with the Helios Mistral WP6 8x42 binoculars. I will go as far as to say I may have (only very rarely) used binos in this class that are as good as these, but never any better. Indeed in my experience the image quality on this bin is every bit as good the better mid-range instruments out there….I thought that the overall look and build quality of the exterior is excellent. Indeed it is as good as many far more expensive optics and for me is about as good as it gets within this price range….I really like the etched metal focus wheel that turns nice and smoothly and has a great feel and action. Similarly the twist-up eyecups are also very good, which combined with their 17.5mm of eye-relief makes them an ideal choice for most eyeglass wearers."
